Continue and Break

In for-loops and while-loops, the continue statement can be used to stop the current iteration of a loop and start the next iteration.

var i = 0
var x = 0
while i < 10 {
    i = i + 1
    if i < 3 {
        continue
    }
    x = x + 1
}
// `x` is `8`


let array = [2, 2, 3]
var sum = 0
for element in array {
    if element == 2 {
        continue
    }
    sum = sum + element
}

// `sum` is `3`

The break statement can be used to stop the execution of a for-loop or a while-loop.

var x = 0
while x < 10 {
    x = x + 1
    if x == 5 {
        break
    }
}
// `x` is `5`


let array = [1, 2, 3]
var sum = 0
for element in array {
    if element == 2 {
        break
    }
    sum = sum + element
}

// `sum` is `1`
